While the bus system may not be as glamorous as the monorail, train or boats of Walt Disney World, it may be one of the most efficient and a testament to what public transportation should be. From the front of your resort you may catch a bus for whichever park you may be visiting, Downtown Disney, Blizzard Beach, Typhoon Lagoon... While Disney has a complicated scheduling system, for the most part you will never wait more than 15 minutes. 

 

When you are leaving the parks you can then find a bus that will take you back to your resort hotel. While parking is free when you are a resort guest, this can still be a lot quicker and easier than driving, as the busses will drop you off directly at the front. When you come back you do not have to deal with a car that has been sitting in the sun all day or the trip out to the parking lot.
